In this paper, the specific heat of saturation salt solution was measured by coolingmethod,and the uncertainly of result was analyzed. It was shown that, the specific heat value of saturation salt solution was approximately 3. 243J/(g · K), absoluteness uncertainty was 0. 261 J/(g · K). The reliability of result mainly depended on the experiment system error and measuring of temperature.
